Strictly Come Dancing duo Russell Grant and Flavia Cacace are to launch their own fitness DVD, Zalza, showcasing their new fitness concept based around dance, available April 12 on QVC.

Zalza, which has helped Grant lose 11 stones since 2009, uses six different dance techniques from around the world, including the Salsa, Cha Cha Cha and the Jive. The pair commented 'We are thrilled to be able to pass on our Strictly experiences which enabled Russell to get fit thanks to Flavia's incredible choreography', and are available for interview.
